Application filed October 17, 1925. Serial No. 63,008.

y"lrhis invention relates to improvements in against the flat bottom of the arm 8. When is pivotally planting iri'a'chinesv and more particularly to improved means for locking'a seed can to -it's`support,one object of the invention bet ing to provide'simple means to lock the seed can toits lsupport and vpermit the can to be readily moved or removed from the planter fol1 the vpurpose o f changing the plates or foremptying or vfilling the can.

A further object is to provide a locking means for a seed can, in which the locking pin or bolt will be held in unlocked position and thus prevented from swinging freely, and in which the holding spring will be 1 gradually compressed when the pin or bolt is being moved from unlocked to looking position.

With these and other objects 'in view, the invention consists in certain novel features of construction and vcombinations of parts as hereinafter set forth and pointed out in the claims. Y In the accompanying drawings, Figure 1 is a vertical sectional view illustrating an embodiment of my invention, and

Figure 2 is a plan view.

In Figure 1 of the drawings, a base or 'support casting is indicated at 1 provided with a spout 2 as shown in Figures 1 and 2. The base casting 3 of a can 4 is mounted 'upon the support casting 1 and is provided with atongue 5 which enters a hole 6 in an arm 7 projecting from the supportinghcasting 1 and in this manner the can is hinged "f tov the supporting casting.

Diametrically opposite the hinge construction above described, the `support casting 1 is provided with a laterally projecting arm 8 and the base casting 3 of the can is provided with a laterally projecting arm 9 which, when the parts are in normal position, overlies the arm 8. The arm 9 on the casting 3 is bifurcated and receives between its members a locking pin or bolt 10 which supported by said arm 9 through the medium of a pin 11. rIhe arm 8 on the support casting 1 is also bifurcated for the accommodation of the locking bolt 10. The locking bolt 10 may be provided at its free end with a head 12 forming a shoulder 13 against which latter, one end of a spring 14 bears. The other end of said spring bears against a plate or disk 15J which, when the parts are in locked position as shown in full lines in Figure 1, bears the locking bolt is in unlocked position it will be held in vertical position -as shown in dotted lines in Figure 1, by the springV 11i `pressing vthe plate 'or disk -15 downwardly on the atupper portion 16 of the arm 9.

The louter end'` portions of the members of arm 9 are curved as `indicated at 17 andthe outer end portions'of the members of varm 8 are curved as at 18,-the curved portions 17-18 of the arms 8 and 9 being eccentric to the pivot mounting of the locking pin or bolt 10.

Then the locking pin or bolt 10 is moved from the unlocked position shown in dotted lines in Figure 1 to the locked positionv shown in full lines in said ligure, the disk' or platev 15 will ride on the curved portions 17-18 of the arms Sand 9 and during such movement of the locking bolt, the spring 14 will be gradually compressed until the locked position of said bolt is reached. Vhen the bolt is in unlocked position as vshown in dotted lines in Figure 1, the spring 14: will be but slightly compressed but it will exert sufficient force to retain the disk or plate 15 in contact with the flat top of the arm 9 and thus yhold the locking bolt in an upright position and preventing it from swinging freely and dangling from the can base casting.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent is:

1. The combination with a seed can and a support therefor, of a pivoted locking bolt connected with the can and cooperable with said support, and spring means operable to hold said locking bolt in unlocked position when the latter is disconnected from the support. v

2. The combination with a seed can and a support therefor, of a locking bolt pivotally connected with the seed can and cooperable with the support, a sprin` oper- 1Go able to hold the locking bolt in locke or unf locked position, and means whereby said spring is compressed during the movement of the locking bolt from unlocked to locked position. j

3. The combination with a seed can, a bottom casting therefor and a support casting, of a bifurcated arm on said bottom casting, a bifurcated arm 'on the support casting, a

locking bolt pivoted in the bifurcated arm 11g on the bottom casting and movable between the members of the biluroated arm on the support casting, a plate on said bolt. and a spring between said plate and the free end of the bolt, said plate being pressed by the spring against the bottom of the arm on the support casting when the bolt is in looked position and said plate being pressed against the top of Vthe arm of the bottom casting when the bolt is in unlocked position.

4. The combination with a seed can, a bottom casting therefor and a support casting, of a bifuroated arm on the bottom casting having a flat top portion, a bifureated arm on the support Casting, a locking bolt pivoted in the bifuroated arm of thev bottom casting and movable between the meinbers of the arm on the support casting, said arms having` ourvedeportions eccentric to the pivot mounting of the looking bolt, a plate on said looking bolt, and a spring between said plate and the free end ortion of the bolt, said spring operable to old the plate against the bottom of the arm on the snpport casting when they bolt is in looked position and to hold said plate against the flat top of the arm on the base casting when the bolt is in unlocked position, said plate being adapted to ride over the curved portions of said arms when the bolt is being moved from its unlocked to its locked position, whereby compressionV of the spring will be effected automatically.

In testimony whereof, I have signed this specification.
